Insulation testers and continuity testers from Megger, Kewtech, Metrel, and Martindale Electric. We are UK suppliers of 17th Edition insulation and continuity testers for electricians, engineers, technicians, service staff and maintenance personel. We can supply you with low cost digital or analogue insulation testers models like the popular Kewtech KT35 Digital Insulation tester and Kewtech KT32 Analogue Insulation test equipment. Metrel MI 2123, TEK 3660.  Megger Insulation Testers at least 10 insulation testers like the MIT300 MIT310 MIT310A - MIT320 - MIT330 MIT220 and MIT 230. Industrial models include the MIT 440 - MIT400 - MIT410 - MIT 420 - MIT430 - MIT40X. Telecoms insulation and continuity testers include the MIT 480 - MIT481 and MIT 485. A low resistance between phase and neutral conductors, or from live conductors to earth, will result in a leakage current. This current could cause deterioration of the insulation, as well as involving a waste of energy which would increase the running costs of the installation. Thus, the resistance between poles or to earth must never be less than half of one meg ohm
